However, it is unclear how the consumption of different vegetables might interact to influence vascular health. This study tested the hypothesis that nitrate-rich vegetable consumption would lower systolic blood pressure but that this effect would be abolished when nitrate-rich and thiocyanate-rich vegetables are co-ingested. On four separate occasions, and in a randomized cross-over design, eleven healthy males reported to the laboratory and consumed a 750\u202fmL vegetable smoothie that was either: low in nitrate (&sim;0.3\u202fmmol) and thiocyanate (&sim;5\u202f&mu;mol), low in nitrate and high in thiocyanate (&sim;72\u202f&mu;mol), high in nitrate (&sim;4\u202fmmol) and low in thiocyanate and high in nitrate and thiocyanate. Blood pressure as well as plasma and salivary [thiocyanate], [nitrate] and [nitrite] were assessed before and 3\u202fh after smoothie consumption. Plasma [nitrate] and [nitrite] and salivary [nitrate] were not different after consuming the two high-nitrate smoothies, but salivary [nitrite] was higher after consuming the high-nitrate low-thiocyanate smoothie (1183\u202f&plusmn;\u202f625\u202f&mu;M) compared to the high-nitrate high-thiocyanate smoothie (941\u202f&plusmn;\u202f532\u202f&mu;M; P\u202f&lt;\u202f.001). Systolic blood pressure was only lowered after consuming the high-nitrate low-thiocyanate smoothie (-3\u202f&plusmn;\u202f5\u202fmmHg; P\u202f&lt;\u202f.05). The acute consumption of vegetables high in nitrate and low in thiocyanate lowered systolic blood pressure. However, when the same dose of nitrate-rich vegetables was co-ingested with thiocyanate-rich vegetables the increase in salivary [nitrite] was smaller and systolic blood pressure was not lowered. These findings might have implications for optimising dietary guidelines aimed at improving cardiovascular health.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-8744","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Sport and Health Sciences, College of Life
